Dear Firefox Staff, i'm having problems on Facebook videos, when i play them, suddenly i cannot move backward or forward the slide-bar of the video... if I want to jump back with the slide bar to start over the video it won't lemme nor forward the video.

This is only happening in firefox i tried to exit from Firefox, deleted the mozilla firefox folder, them reinstall firefox Also i tried to start firefox without any addons, and tried incognito mode and problem persist


Thats the bar that i cannot move, i just can play the video and pause.

uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files and C:\Program Files(x86) Then restart system. Then run Windows Disk Cleanup. Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do : https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles
